Fyi, I'll be picking this up again this weekend.

Release candidate 1 is up:
https://github.com/brianfrankcooper/YCSB/releases/tag/0.16.0-RC1

As a reminder, testing a given binding should at a minimum run through a load and a run phase. Ideally, one should go through the recommended sequence of workload steps from the "Running the workloads" section of the Core Workloads documentation.

known issue for mongodb clients talking to AWS DocumentDB #1314

[busbey]

checked field name prefix configuration on OS X using the basic binding. worked fine for bin/ycsb but looks like #908 is still an issue.

huh. an issue if running ycsb.sh after running ycsb. I'll put up a PR. probably this has been broken since 0.13.0.

[robert-s-lee]

created patch #1335 to fix jdbc/README.md format issue from #1220

[busbey]

#1335 is merged now, I need to cherry-pick it back to the 0.16.0 staging branch still

[busbey]

Assuming the changes needed to publish to Maven Central (#1340) land on the master branch I'm going to just publish 0.16.0 as a "not vetted" release, as we did for 0.13.0. That means we'll need to make sure the stuff listed above gets checked for the 0.17.0 release.

[busbey]

also #1335 is on the 0.16.0-staging branch.
